Shutter is actually the 0.7 version of what was once known as GScrot—and, boy, did that name need changing. The free app is a serious boon to bloggers, technical writers, or anyone else who needs to show off part or all of their Linux desktop. Shutter lets you pick which image format to paste or save your PrtSc-triggered shots to (though you can set other hotkeys for Shutter), which app to open them in, pre-set compression or thumbnail resizing, and generally automate all the stuff you're used to doing by hand after a screen grab. Can't manipulate your desktop to show a certain window without it being covered? Shutter can focus its capture on any running screen element, and you can stack your different screenshots in tabs. Site owners and bloggers will dig the auto-uploading and saving tools offered.

Shutter is a free download, and should work on most GNOME-based Linux distributions. Ubuntu-based repositories and source packages are offered at the link below.
